Medical dressings

There are many literature reports that concern the physiological safety of silicone oils used in ointments and skin protection creams, as well as in various forms of Silicone implants can be used for insertion into the human or animal body. Also were Silicones already used for bandages. For the investigation of possible uses of silicones for Much work has been expended, and after, the treatment of skin diseases and burns in humans and animals From a medical point of view, there are several types of silicone that are suitable for such treatments.

Especially when treating burn wounds, it is desirable to keep the wounds as sterile as possible keep. In the case of severe burns, it is also desirable to give the patient some freedom of movement to give so that the burned parts of the body can be kept moving to reduce stiffness or

109882/1379

the loss of mobility in joints when burned To prevent limbs. This is particularly important in the case of burns on the hands, arms, feet or legs. in which a permanent handicap as a result of burns can often be observed.

Gauze bandages have already been used to prevent contact with ointments and creams containing silicone or other treatment agents to allow with the burned areas. However, these gauze bandages have various defects. They limit the body's ability to move, and they must be attached to the application site in some way usually by means of adhesive tape, which, however, cannot be placed directly on the burn wound. aside from that they tend to stick the liquid exudate from the burn wound and are only difficult and painful to remove. In addition, they are difficult to keep sterile.

The present invention therefore relates to medical dressings which are particularly suitable for burn wounds on body extremities are suitable, and with which the mentioned and other disadvantages can be avoided.

The medical bandage material according to the invention consists of a liquid-impermeable, bag-like envelope

made of flexible material with silicone oils inside, possibly * along with other common wound treatment agents and bundles of absorbent, fibrous or sponge-like, compressible material Contains material.

In use, the wrapper is cut open on one side and placed over the burned limb so that the burned Is loosely wrapped in it. The covering is attached to the body at a point away from the wound. By Movement of the injured limb through the patient compresses the absorbent material, thereby releasing the injured limb Limb is kept in motion, and on the other hand the liquid circulates over the burned surfaces.

Details of the dressing material according to the invention are explained on the basis of the attached drawings:

Figure 1 is a perspective view of a sealed sterile dressing and

Figure 2 is a perspective view of the bandage in use on a patient's hand.

From Figure 1, the sack-like cover 11 is made of the liquid-impermeable Material, e.g. made of plastics, can be seen. Inside the shell 11 there is a certain amount Liquid 12 and a bundle of absorbent, fibrous

10988 2/1379

or sponge-like material Ij5, e.g. absorbent cotton, to see.

Preferably, the liquid 12 is a silicone oil of sufficient low viscosity so that it can flow easily.

During the production of the dressing material according to the invention, the envelope 11 and its contents are sterilized and then the Sealed envelope. During use, the cover is cut open at one end and the body part to be treated is inserted into the open end inserted. Then the open end is attached to the patient's body, for example by adhesive tape 14, what can be seen from FIG. The attachment point on the body is expediently at some distance from the wound. The bundle of fiber material I ^ can be expressed by grasping will. For example, the hand muscles are kept in exercise by expressing with the hand. Through this process becomes however, it fulfills another function as the liquid is squeezed out of the fibers and over the damaged areas is directed. When the pressure is released, the excess Liquid easily absorbed by the absorbent material. The result is a pumping effect. This is additionally a Filtrationwiukung achieved, because suspended from the liquid when flowing in and out of the fiber material Particles are trapped so that the liquid is clean

109882/1379

will hold. In this way, moisture and exudate are removed absorbed and held in place by the absorbent material.

In a particular embodiment of the dressing material according to the invention, the shell made of polyethylene, the fibrous material of absorbent cotton and the liquid is a silicone oil having a viscosity of 100 cSt / 25 C ⁰ (Dow Corning Medical Fluid J56O). This liquid is a dimethylpolysiloxane oil end-blocked with trimethylsiloxy units, which falls under the general designation "silicones" or "organosiloxanes". It corresponds to the general formula (CH,), SiO [(CH,) _o SiOl Si (.CH,) ,, where the value of

χ indicates the chain length and is directly related to the Viscosity stands. Silicone oils of this type are described in the literature, so that the description in detail can be found here unnecessary.

Of course, are of the dressing material according to the invention numerous modifications and variations are possible, since both the material of the covering and the fiber material and the type of liquid can be varied. Together with the liquid, various medicinal agents, which are usually used for wound treatment, may be added Find use, be used. The size of the envelope can also be adapted to the particular application will. The amount of liquid in the envelope must be used to
